Answer:
24+6pi
Step-by-step explanation:
the sides on the left and right added up are
12+12=24.
the formula for perimeter of a circle is 2πr.
3 is the radius, making the equation
2π3 which is 6 pi.
for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.
the bottom cut out half would also be 3 pi.
in total, we would have 24+3pi+3pi which would lead you to 24+6pi.
The given equations are
5x + 7y = 7
3x - 2y = 9
As a matrix equation,
A = [5 7
3 -2]
X = [x
y]
C = [7
9]
That is
a =5, c=7; and b=3, d=-2
a - b + c + d = 5 - 3 + 7 + (-2) = 7
Answer: 7
